Small overlap front: driver-side

Rating applies to 2017-21 models

Tested vehicle: 2017 Chevrolet Bolt EV Premier 4-door hatchback

The Chevrolet Bolt was introduced in the 2017 model year. The car is a plug-in battery-electric vehicle with no gasoline or diesel engine to help power the car.

Action shot taken during the small overlap frontal crash test.

The dummy's position in relation to the door frame, steering wheel, and instrument panel after the crash test indicates that the driver's survival space was maintained well.

The frontal and side curtain airbags worked well together to keep the head from coming close to any stiff structure or outside objects that could cause injury.

The driver's space was maintained well, and risk of injuries to the dummy's legs and feet was low.

Lower leg/foot
Passenger restraints and dummy kinematics The dummy’s head contacted the right side of the frontal airbag but began to move into the gap between the frontal and side curtain airbags, leaving the head vulnerable to contact with forward structure. The inflated side curtain airbag has sufficient forward coverage to protect the head from contact with side structure and outside objects.

Driver restraints and dummy kinematics

Action shot taken during the passenger-side small overlap frontal crash test.

The dummy's position in relation to the door frame and dashboard after the crash test indicates that the passenger’s survival space was maintained reasonably well.

The dummy's head contacted the frontal airbag so far to the right that it moved into the gap in coverage between the frontal and side curtain airbags.

The passenger’s space was maintained reasonably well, and risk of injuries to the dummy's legs and feet was low.

Action shot taken during the moderate overlap frontal crash test.

The dummy's position in relation to the steering wheel and instrument panel after the crash test indicates that the driver's survival space was maintained very well.

Smeared greasepaint indicates where the dummy's head contacted the side curtain airbag during forward movement and rebound.

Intrusion into the driver's space was minimal, and all leg and foot injury measures were low.

Overall rating
Distance at which headlights provide at least 5 lux illumination:

Low beams
On the straightaway, visibility was good on the right side of the road and fair on the left side. On curves, visibility was good on both right curves, fair on the sharp left curve and inadequate on the gradual left curve.

The low beams never exceeded glare limits.

High beams
On the straightaway, visibility was inadequate on both sides of the road. On curves, visibility was good on the gradual right curve and fair on the sharp right and both left curves.

High-beam assist compensates for some limitations of this vehicle's low beams on the straightaway and on both left curves.

Distance at which headlights provide at least 5 lux illumination:

Low beams
On the straightaway, visibility was good on both sides of the road. On curves, visibility was good on both right curves and fair on both left curves.

The low beams created excessive glare.

High beams
On the straightaway, visibility was good on the right side of the road and fair on the left side. On curves, visibility was fair in all 4 tests.

High-beam assist compensates for some limitations of this vehicle's low beams on both left curves.
